Definitions

  • This invention relates to a deep ribbed composite thermoinsulating panel.
  • Deep ribbed composite thermoinsulating panels comprising two metal facings and an insulating layer interposed therebetween.
  • the two facings are preferably in the form of galvanized steel, aluminium, copper or stainless steel sheet, and the insulating layer is of foamed polyurethane or mineral wool. They are mainly used in roof construction.
  • panels see for example CH-A-583 354.
  • panels comprising a solid longitudinal rib (male rib) along one edge and a hollow longitudinal rib (female rib) along the opposite edge.
  • male rib solid longitudinal rib
  • female rib hollow longitudinal rib
  • a drawback of these known panels is that their installation requires the use of screws, which pass through the tow facings and are fixed into the underlying purlins. There is hence the need to drill the panel, involving the risk of infiltration through the roof when formed.
  • the panels have to be arranged with a slope of not less than 7°.
  • a further drawback is that the screws for fixing the panels to the purlins must be of special type, in particular with their head comprising a plastic coating, to prevent any alteration with time due to the climatic conditions to which they are exposed.
  • a further drawback is that as the joint between adjacent panels is made substantially at the purlins, to which both are fixed, there is no guarantee of tight fitting between the panels in those regions removed from the purlins, because the inevitable deformation to which the panels are subjected, for example because of their weight, means that perfect mating between their adjacent edges cannot be ensured.
  • thermoinsulating panel as described in claim 1.
  • the panel according to the invention comprises an outer metal facing 2, an inner metal facing 4 and a layer of insulating material 6 interposed between the two.
  • the outer facing 2 is in the form of sheet metal, preferably of galvanized steel, aluminium, copper or stainless steel, either bare or prepainted on its inside to facilitate gripping by the layer of insulating material 6. It comprises tall longitudinal ridges 8 the purpose of which is to stiffen the product and to create channels for dispersal of rain water, and also comprises light transverse ridges 10 having the double purpose of stiffening and of making slight face planarity defects.
  • the panel comprises a single inner longitudinal ridge 8 of trapezoidal shape, filled internally with the same thermoinsuIating material as forms the layer 6.
  • the inner facing 4 is of flat sheet metal, generally of lesser thickness than the outer facing 2 and preferably of galvanized steel or aluminium sheet, bare or prepainted on its outer side and prepainted on its inner side to facilitate gripping by the insulating layer 6.
  • the insulating layer 6 can consist of a single material or can be composed of several materials; the most commonly used materials are foamed polyurethane and mineral wool, preferably of orientated fibre type.
  • the outer facing 2 extends beyond the longitudinal edge of the panel to form a female rib 12 which on installing the panel is made to embrace, as described hereinafter, the male rib 14 provided along the opposite edge of the adjacent panel.
  • the female rib 12 has an inwardly bent free edge 16 and, in a position facing this, an undercut 18.
  • the insulating layer 6 extends in proximity to the inner facing 4 to form a sort of longitudinal ridge 20 covered by the facing itself.
  • the male rib 14 provided along the opposite edge of the panel differs from the central trapezoidal ridge 8, and in particular comprises in that side facing the panel interior a groove 22, and presents on the opposite side a longitudinal cut-away part 24, completely covered by the outer facing 2 and having its free edge 26 bent upwards to externally bound said cut-away part 24.
  • the insulating layer 6 comprises a further longitudinal cut-away part 28 substantially complementary to the ridge 20 provided along the opposite edge and, as in the case of this latter, covered by the inner facing 4.
  • the elastic plates 30 are fixed to the lower side of the outer facing 2 at equal distances apart, preferably by a continuous automatic process.
  • the bent outer edge 16 of the female rib 12 of the second panel, held inclined to the first panel, is then engaged in the longitudinal groove 22 of the male rib 14 of the first panel, after which the second panel is rotated, while maintaining the engagement, until it assumes a position coplanar with the first.
  • the plates 30 are made to yield elastically towards the interior of the cut-away part 24 until the coupling tooth 32 of each plate 30 engages in the undercut 18 of the female rib 12 of the second panel, the ridge 20 of which engages in the cut-away part 28 of the first panel.
  • the second panel On termination of this operation, ie when the second panel rests on the purlins 34 and is coplanar with the first panel, its ridge 20 is engaged in the cut-away 28 thereof and the undercut 18 of its female rib 12 is engaged by the coupling tooth 32 of all the elastic plates 30, the second panel can also be fixed by screws 36 to the purlins 34, to allow the third panel to then be installed, and so on until the roof is complete.
